Just noticed my front tyre is pretty scolloped on one side (Right side as you sit on the bike)..
What causes a wear pattern like that?
I am replacing both tyres later this week (Not friggin Michelins at the price they are now £435!!!)..
The tyres are Michelin Pilot Road 4 by the way.
Any ideas?

Underinflated and roundabouts can do that,but that's just my experience on a Daytona 675 that showed the same symptoms when I bought it.
Perhaps you plan your routes so you only turn right? Try doing the same but with only left turns to extend tyre life :rofl3:
PR 2,3,4 well known for it. I had 3, worst tram trafficking tyre. Angels solve the problem.

I had it on Angels as well.
It can't be avoided as it is caused by the camber of the road.
Roads aren't flat they are designed so that water runs away from the centre to the sides.
This road camber causes the front tyre to wear with a scallop as the front tyre is being pushed during cornering.
Just replace the tyres before the handling completely deteriorates.
Michelins do that really badly and are way too expensive these days too.

Not all Michelins do that, not even slighty ;-)

Those don't have any tread on!
I think it's down to the tread blocks moving under load

Grog your soooo right about them tramlining !!!
Just looking at one of your other posts Simon, you said your bike was sat for 5 years prior to you getting it, so just wondering how old those tires on it are? Could be down to old rubber as well. Be interesting to see the date code.
Speedy that tyre looks completely shagged. I've had three sets of PR4's and never seen that. On my second set of Road 5's no problems with those either.
I'd be checking to make sure the wheels are in line, the front end assembly and forks were all square, settings matching and free. To me it looks like more than a Tyre issue.
Si, I recall you leave the bike outside overnight, I reckon it could be the side that's accessible to rats, squirrels & badgers & they're gnawing on it overnight . . . :whistling: :stir:
Sure looks bad though.
Agree Angels do scallop but last one took 18th ks to do it. My mates bike with Bridgestone, gone after 5th, not good enough i reckon
@Speedy1959 I've just checked your pic of the front tyre.
That's probably the worst I've seen.
Was it a gradual thing or overnight? Ie did handling deteriorate or just whammo?
I have so many questions lol however I'd start with the fork settings & work up from there.
Good luck 🙏🙏🙏
Tyres?
I love S22's, but just looking up the price for another pair fitted... AU$610... (£320).
Fark !
In my experience, tyres that work (or not) on one bike can be brilliant (or not) on another. I had Michelin PR5's on my Triumph when I owned it and they were brilliant, no wear issues at all - yet the original front Metzeler Tourance tyre it came with as OEM from the factory had lost all tread on the RH side by just 2,250 miles and had to be replaced. I'm currently running Michelin Road 6's on my GS and getting excellent mileage from them also.
What works on one, may not on another.
Tyres these days though in general are not cheap whichever make you go for!!!!
Just re-read this article which is as true now as it was when it was first published https://gsx1400owners.org/forum/index.php?topic=5909.0

Col,
Checked the date stamp yesyerday and its the 25th week of 2018 !
5 Years, not horrendously bad. Prob getting near for a change if it hadn't scalloped anyway, eh.

Totally agree Col..
Just waiting for my Bike tyre place to source a rear Avon Storm 3DXM.. Hes got the front in stock..
Like most things British that were good Avon have apparently been taken over by Goodyear (apparently) and are to move the production the France (I think)..
The Storm is being ceased.. Thats a pity as it got very good reviews and was a fair bit cheaper that Michelin.

All tyre companies globally entangled with share holdings in each other. Similar to auto industry as a whole. The big companies keep getting bigger 💰💰💰
I had a search on cupping/ scalloping. Road camber sure is one problem, just how it is. Other cause, tyre bouncing on road, tiny but causes it. Just me but, that means perfect fork oil, weight and condition. Springs need to be set, otherwise bounce, thats a normal. Less than more spring load. Rebound settings the most important they keep the tyre in contact with road. MCN settings very harsh, reckon no chance for tyre to survive. Mine was all set up for me, initially i thought way too soft, after a few rides, much more enjoyable and sure can notice front tyre just sticks to road. My front tyre lasted a long time, cupped towards end, 18 th ks. No dive, no pogo stick, much better. My 2 bobs worth.
I will be having the Avon Storm 3DXM fitted front and rear on Wednesday..
I shall report how I find them.
S.
Got them on two of my bikes, love 'em. Ride better and outlast so called better makes.
The other two have Avon Cobras, well the HD has the newer cobra chromes.
Can you tell I'm an Avon fan? I really hope they aren't ruined when production goes abroad
Also got them on a couple of bikes :onya:
Never tried modern Avons, will see prices against Pirelli next set. I remember back early 70s, not a lot of choice then. Slippery Jap tyres, Bridgestone, Inoue, Yokohama. Dunlop were best,K81/ TT100 from memory. Avon were a big choice, rear used to wear to totally flat across. No idea why but sure was a ride on the edge. Cant rem if anyone used European tyres, Pirelli, Michelin etc. They all used to wear out so quick, bad on our 750s then Z1 came along. We rode one weekend and mate wore his out in 2 days. Much improved these days. My first two GT750 came with Inoue from new, just go and rub grease on your current tyres, about the same. Two front discs, no tyre grip, was fun. Hope im not boring you Blokes.
Not at all Grog, feel free to carry on if ya like . . . :onya:
My 14 runs on Avons, love em. Made just down the road, it's a shame the factory is closing.
